DfE told us that its CDC1 programme involved giving a ‘grade’ to every building component within each school. There were four available grades, from A to D, with grades C and D denoting a less than satisfactory condition. DfE explained that it gave a grade C to 2.1% of components, and a grade D to 0.3% of components. It accepted that, while these numbers seem low, they still represent a significant number of schools, and large numbers of pupils are learning in those schools. DfE said that it is using its second Condition Data 41 TSB0007, The Confederation of School Trusts, The condition of school buildings, 13 July 2023 42 C&AG’s Report, Figure 5; paras 2.9, 3.11 43 July 2023 session, Q 72; Correspondence from DfE to the Chair of the Public Accounts Committee, 7 September 2023 The condition of school buildings 17 Collection programme (CDC2) to check whether it can address those components in the worst condition.
